Product Description:

The MDD071B-N-030-N2S-095GR0 is a brushless servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Paired with digital drive controllers, the unit supplies tightly regulated torque and speed so automated axes, packaging stations, and small machining spindles can follow programmed motion profiles with repeatable accuracy in industrial automation lines. Its brushless construction supports responsive motion control and reduces wear associated with mechanical commutation. This type of motor is commonly used where fast acceleration, stable low-speed operation, and accurate position tracking are required across repeating duty cycles.

Its rated operating speed is 3000 rpm, meaning the rotor can turn at three thousand revolutions per minute while remaining synchronized with the commanded electrical frequency. Under standstill conditions, the electromagnetic system delivers 4.4 Nm of continuous torque, so the motor can support a steady static load without thermal overload. A machined flange provides a centering diameter of 95 mm for concentric, play-free coupling to gearboxes or mounting faces. Power and feedback connectors are located on the right side of the housing, which can simplify cable routing in compact machine layouts. Position information is returned through digital servo feedback, allowing the controller to regulate both speed and position with high resolution.

A shaft seal helps keep coolant splash and fine dust out of the bearing chamber, which supports lubricant retention during operation. The motor is supplied without a blocking brake, so holding force during power-off must come from the drive or an external mechanical device. Its plain shaft suits clamp or shrink-fit couplings that require a smooth contact surface. Because the output surface is smooth, couplings can be installed with accurate alignment and without the backlash associated with keyed connections. The standard housing, along with the B motor length and 071 frame size, gives the motor a compact profile for narrow machine spaces, and the balanced Class B rotor helps maintain smooth running.
